We own several vegan cookbooks as well, and have been leaning on this one pretty heavily since we got it. Everything has been quite tasty, albeit slightly labor intensive.
Since it's produced by America's Test Kitchen, I'm more inclined to trust the recipes at face value with little modification. Other vegan cookbooks I have found require adjustments to get the flavor correct.
I've not read this particular cookbook, but anything from America's Test Kitchen is generally leaps and bounds ahead of any other cookbook you've ever read. They use a lot more cooking theory and testing methodology, compared to "grandmas old recipe" or similar old wives tales.
The flip is like any analytical process, the results vary based on the scope.
You really need to watch the show, as the sometimes they make assumptions that don’t make sense to me that drive the whole process. That isn’t captured in cookbooks. They get the best output based on the criteria set.
